I, Ame Nrcrroms NAIOLEON Ansm, formerly of Albany, State of New York, temporarily residing in Montreal, Dominion of Canada, have invented a Submerged-Peat Shovel,'of which the following is a specification.

The nature of myinvention consists in animplenient for extracting peat from the bog, even when .it

is underwater, founded uponthe principle of thejscrew or anger, -wi th a special arrangement for admitting water or air under the instrument when it is being raised with its load, and thus preveutingthe forma-- tion of a vacuum,-to overcomewhich, would require.-

otherwise much power. 7

Figure 1 is a plan of the screw-blades, two of which bear eccentric enclosing-wings.

Figure 2 is a perpendicular section of thesame, from Ito J.

Figure 3 shows the position of the shovel when it is raised; canted, and upset to discharge its load.

A B O D are the screw-blades, for cutting into the peat and filling the shovel, by merely revolving it-in the direction 0 the arrow e. Their forward edge is lower than thei back edge, each thnsforming an in- This arrangement has for its object to contract the I lump of peat at/each revolution of the shovel, sothat being smaller than the hole from which it is out, four vacant spaces, a a a" a, are left around it, through which water or air can penetrate and replace the peat,-

thus preventing the formation of a vacuum, and therefore facilitating considerably the raising of the load.

Thesewings are also intended to support the load after it'is raised, and the shovel canted to bring it over a soow or the solid surface of the bog.

At'lgthreads are cut-to receive a nut, which fastens The handle is square where it fits into the hole then itis round upto P, so as to allow the free bracket M to turn" and'take' any position around ithe handle.

Above that the; handle is square, in order to fit the cross-arms N, by-whioh the shovel is rotated. 4 The upper end ofrthe handle is provided with an eye, I", to which istied. the rope or chain 1, which serves to cant the shovel.

The rope m is passed over a pulley suspended from a movable arm or running hook, and lowered or raised at will, by hand or machinery.

When the shovel is lowered 'upbdthe peat in an upright position, men turn it in the direction ofthe arrow; then it gradually sinks, cutting a circularhole, a.

Whenaliove the water, the men take hold of the rope I and cant the shovel, with the wings down, so as to support the load. They then swing it over the loading-scow or the shore, and turning it so that the wings areabove, the load P falls by its own weight, as seen in fig. 3. v
